Rav Willig discusses very thoroughly the character traits to look for in choosing a wife. He stresses the importance of focusing on good character, and to not marry for money. He points out that aside from the obvious emphasis on Chesed in the parsha of Eliezer and Rivka, there is also a very strong emphasis on Tznius. Rav Willig develops this theme based on the beautiful comments of the Kli Yakar on this parsha in the Chumash. He also emphasizes the crucially important role of Tefillah.
